From a very young age, astronomy has been a subject of interest to me. However, I was also curious about what makes up everything. This is a naive attempt from my end to explain electromagnetism and quantum mechanics, the world of small things. I am unsure how many parts it may split into, as I am just going with the flow here.

Part one

How do we communicate?

It all began during my bike commute to the workspace. I often use this time to listen to podcasts (I couldn't listen to music these days, maybe just a phase!?). One one of the days, I tried to use ChatGPT's voice mode to talk to, but it had severe latency. My immediate thought blamed the 5G network, however a part of my quirky brain briefly wondered if there is a very teeny-tiny possibility that Bluetooth could buffer the data and stream it back with a delay, like how queues work. I knew the question was stupid and highly unlikely but I still went ahead and tried to justify to my other half of the brain on why that cant be the case.

In order to justify, I had to learn how exactly Bluetooth(BLE) works and if there is working memory as such that partly buffers the stream. Apparently there is one, but the buffer is too negligible to notice for any such real world scenario and plays no role in delays. So, its mostly fire and forget. I learned that BLE transmits via radio waves (overlaps with 2.4 GHz microwave frequency - same as our WiFi), so the bottleneck must obviously be my internet connection after all.
